Detailed explanation-1: -In judgmental sampling researchers select units from the population based on their knowledge and judgement about the unit. This kind of sampling does not provide equal probability of a unit being chosen.

Detailed explanation-2: -Non-probability sampling is a method of selecting units from a population using a subjective (i.e. non-random) method. Since non-probability sampling does not require a complete survey frame, it is a fast, easy and inexpensive way of obtaining data.

Detailed explanation-3: -Quota sampling is a non-probability sampling method that relies on the non-random selection of a predetermined number or proportion of units. This is called a quota. You first divide the population into mutually exclusive subgroups (called strata) and then recruit sample units until you reach your quota.

Detailed explanation-4: -Major probability sampling methods are simple random sampling, stratified random sampling, and Cluster sampling, and Systematic sampling.

Detailed explanation-5: -Quota sampling is defined as a non-probability sampling method in which researchers create a sample involving individuals that represent a population.
